Lucas produced this strange animated movie, and I've always loved it. It has a tortured history. It got censored, existed in two or more versions for a while, and has been out of print for like forever. If you haven't seen it, chances are you won't...

Unless you watch this wonderful fan-made reconstruction of it on youtube: http://www.youtube.com/watch?v=9b-e4Bz4rXM

My local video store carried an real old copy of this for years. I rented and watched it for the first and only time about 12 years ago. Very different movie. Can't say I loved it. It was interesting but pretty obscure in its approach.
